bioXell S.p.A (CH) - BioXell reports top-line OAB Phase IIb results

The urodynamic trial was conducted in 257 patients treated for 4 weeks in a multi-centre, double blind, placebo controlled study. A statistically significant effect on the primary endpoint, the 'change in volume at first involuntary contraction', was not achieved. A statistically significant improvement in 'bladder volume at first desire to void' was observed in the intention-to-treat population (ITT). Numerical improvements in most other urodynamic parameters compared to placebo were observed but did not reach statistical significance. Numerical improvements were also seen for the key symptoms of OAB in all treatment groups. A statistically significant improvement in incontinence episodes was observed in the modified-intention-to-treat (MITT) population. There was a strong dose related trend in the improvement in Patient's Perception Bladder Condition (PPBC) in the ITT population which reached statistical significance in the per protocol (PP) analysis.

"The results on the primary endpoint are disappointing," remarks Francesco Sinigaglia, CEO, "Data on the secondary endpoints are encouraging and we will be discussing the full data set with our experts and investigators in the coming weeks."

BioXell is currently performing further analyses on the data. A full analysis of the Elocalcitol OAB data will be presented in the course of the Annual General Meeting and the Analyst Presentation in Zurich on April 30, 2009.

To discuss the top-line OAB phase IIb results as well as the 2008 Financial Results (to be published on April 9, 2009), BioXell will hold a:

About the OAB Phase IIb trial
The OAB trial was a urodynamic, multi-centre, double-blind, placebo controlled study in which 257 patients were randomized into three groups (placebo, 75mcg, 150 mcg), and treated daily for 4 weeks. The primary endpoint was to evaluate the effect of Elocalcitol on bladder volume at the first involuntary detrusor contraction, following 4 weeks of treatment. Secondary endpoints included additional urodynamic parameters, symptoms severity and Patient's Perception of Bladder Condition. The trial was performed in 47 centres in the United Kingdom, the Netherlands, Italy and Eastern Europe.
